There are many different types of velomobile. My wife and I own a Flevobike Versatile.

@Gail's ManAbout the 'motorcycle side car': A year or 3 ago my wife and I parked our bicycles (she had her normal recumbent, I was with my velomobile) at a shopping mall. They were standing very close next to oneanother. A woman said to her little daughter: "Look, a bike with sidecar". So you're not the first to mention that.

@Z:What do you mean by 'very fitting'? You think it's rather small? People of 2 m in length fit into the Mango (and Quest and Versatile and.... many other types of velomobile)
